Embodiment Construction
[0027] Embodiments of the present invention are described in detail below:
[0028] like figure 1 As shown, a process method for slag removal and reinforcement at the bottom of a cast-in-place pile, comprising the following steps:
[0029] S1: Open at least one slag cleaning hole at the top of the pile body, and ensure that the slag cleaning hole extends to the sediment layer at the bottom of the pile;
[0030] S2: The slag cleaning equipment is installed in place, and the water and gas pipes are extended from the slag cleaning hole and the nozzle is close to the bottom of the hole;
[0031] S3: Turn on the water supply equipment, and perform high-pressure water jetting to the sediment layer at the bottom of the pile through the water pipe to complete the first slag removal treatment;
[0032] S4: Turn on the gas supply equipment, pass high-pressure gas and high-pressure water jet to the sediment layer at the bottom of the pile through the water and gas double pipes, and use...
